VAPOR ELECTRIC DEVICE.

Specification of Letters Patent.

Patented April 27, 1909.

Application filed November 21, 1907. Serial No. 408,126.

To all whom it may concern:

Be it known that 1, PAUL ALBERT HU- GUENIN, a citizen of the French Republic, residing at .219 Rue de Vaugirard, Paris, France, have invented certain new and useful Improvements in Vapor Electric Devices, of which the following is a specification.

My invention relates to a device for automatically starting a mercury vapor apparatusby tiltin the same.

he nove features of my invention are pointed out in the appended claims. T e invention itself will be better understood by reference to the accompanyin 'drawing.

Figure 1 is a diagram showing the mercury. vapor device before starting same; Fig. 2 is a diagram showin Y the dev ce after the starting 0 eration; an Figs. 3, 4 and 5 are diagrams s owing in detail the parts of a cut-out device to cut out current from a solenoid after same has started the apparatus. The apparatus is pivotally suspended at an an'le to the horizontal. Dis lacement from t iis position is accomplishe b a rod attached to the core ofa solenoid. The current when turned on energizes this solenoid and by an upward movement of the rod reverses the inclination of the apparatus, and starts the same. Instead of employing a special magnetic device later to cut out the solenoid resistance from the circuit, the change of position of the apparatus itself effects a chan e of electrical contact so astd short-circuit the solenoid, or, partially cut it out of circuit if so desired.

Fig. 1 shows the mercury vapor device, as for example, a mercury vapor lamp con sisting of a tubeor container 1 containing mercury or other liquid with suitable electrodes 2 and 3, supported by a suitable frame work 4. ,This frame work is pivotally suspended by a fixed bracket, a broken-off end of which is shown at 5. The pivota frame work is attached by means of a link 6 .to the core 7 of the solenoid 7, by which means it may be moved.

The fixed supptprt or bracket for the frame work, as shown est in Figs 3 and 5, carries a disk 8 with twoelectrically insulated contacts 9 and 10. The frame work 4 itself carries an adjacent disk 11, provided with an electrically insulated contact 12, which is best shown in-Fig. 5 and indicated by a dotted circle in Fig. 4'. This latter contact .12

is pressed against the contacts 9 and 10 by means of a spring 13 or other suitable (levice. Electrical connections, as shown, will be explained in connection with the operation of the device.

When connection is made the current passes through the solenoid 7, which possesses enough inherent resistance to en-ab c it to serve as a steadying resistance, though it may be sup lemented by an external resistance ]9,an( from thence is conducted by 14 to electrode 2, of the apparatus. From this electrode connection is made to the movable contact 12 oftlie cut-out device by means of 18. -(lontact 12 is diagrammatically indicated in Figs. 1 and 2 by means of a dot. This contact, in the positions shown, is spring-pressed against t to contact latter is permanentlyconnected through conductor 15 to the sup 1 main going to the opposite electrode 3 oi tiie a aratus, A complete circuit is thus estal) ished. The current energizes the solenoid 7, causing link i) to draw the apparatus, say a mercury vapor lamp, to the position shown in Fig. 2. Because ol the abovc-lnentioucd displacement of the tube, the contained mercury has been t), which caused to flow along the length ol'tlic tube est-ablishing a coin )lete circuit, and later breaking this met-a lic connecticnas the in clination increases in the opposite direction. The are formed across the broken ends of the mercury stream, continues as the break lengthens.

When the tube or other device, has come "to the position indicated by Fig. 2, the following changes have taken place in the position of contacts: Electrical connection from electrode 2, which formerly was made with contact 9, is now made with contact 10. This contact 10 being permanently connected by conductor 16 with an intermediate point 17 of the solenoid, partially short cir cuits thesolenoid. The current assin through the entire solenoid, goes rom the point 17 at once to electrode 2, then instead of through the tube and out at electrode 3,

which is connected to the positive supply main as above stated.

When the apparatus is cut out of circuit it may bearranged to return to its original 0-. sition, Fig. 1, by means of gravity or otlier suitable means.

What I claim as new and desire to secure by Letters Patent of the United States, is,

1. A me'rcu'ry vapordeviceoccupying an inclined position and suitably "pivoted, the

. said device comprising a container and elecelectrically insulated contactsliding over said fixed part. y

3. The combination of a vapor-electric device having a plurality of electrodes, electro:

magnetic means for'tilting the device, there;

by starting the same, and mechanical means for placingthe vapor-electric device during the starting operation shunt part of the startin means, then. opening the shunt, and fina y short circuiting at least a portion of said starting means.

or' the solenoid operated by' movement when the envelop is sition.

4. The combination of a pivotally-supported envelop containing electrodes, electromagnetic meansfo'r mechanical means actuated by the'mov'ement of said'envelop least a part of said electromagnetic means '5. The combination of, a mercury-vapor device, an electromagnetic tiltinfidevice for establishing and breaking meta ic connection between the electrodes ofthe mercuryvapor device, and mechanical means for including a part of the circuit of the tiltingdvice in series :with the'mercury-vapor device when the latteris tilted to theoperativepo- In witness whereof, I have hereunto set my hand this fourth day of ovember, 1907.
